FLEXIBLE HARROVI.

Application filed October 1, 1914.

To all whom it may concern Be it known that 1, FREDERICK C. WAnNn, acitizen of the United S ates, residing at Mansfield, in the county ofBichland and State of Ohio, have invented certain new and usefulImprovements in Flexible Harrows, of which the following is aspecification.

My invention relates to improvements in flexible barrows, and moreparticularly to that class or type which are adapted to be collapsed orfolded up so as to occupy but little space in shipment or transportationand at the same time protectthe harrow teeth from injury either bycontact with each other or by engagement with external objects.

The primary object of the invention is to provide a generally improvedharrow of this class by the provision of improved link connectingbearing members adapted to detachably connect the ends of the links orreach rods and by engagement with the latter limit the rocking movementsof thetransversely extending tooth carrying bars whereby when theflexible harrow is drawn from one end the teeth will stand at rightangles to the line of draft for the normal orpulverizing operation ofthe harrow, and when drawn from the other end, the teeth will bepermitted to assume a slanting position rearwardly as in clearing theharrow teeth of trash, smoothing, and for transporting the harrow forshort distances.

A still further object is to provide a more perfect flexibility betweenthe parts and yet carry the teeth in a uniform position relative to theline of draft by the provision of im proved link or reach rod connectingbearing members adapted to eliminate friction and at the same time forma more perfect bearin connection between the adjacent links or reachrods. 7

A still further object is to improve and simplify the assemblage of theparts.

.Vith the above mentioned and other ends in view, the invention consistsin the novel construction, arrangement, and combination of partshereinafter described, illustrated in one of its embodiments in theaccompanying drawings, and particularly pointed out in the appendedclaims.

Specification of Letters Patent.

Patented Mar. 2, 3 3915..

Serial No. 864,3?8.

Referring to t .e drawings, forming a part of this specification, Figure1, is a side elevation of a flexible harrow constructed in accordancewith this invention, the teeth being shown slanted rearwardly from theend of draft. Fig. 2, a detached isometric view of one of the improvedlink bearing members or clips and illustrating the relative position andmanner of assembling the same with the adjacent parts,'including a linkand draft hook, such as shown at the ends of the harrow in Fig. 1. Fig.3, a detailed top plan view of the improved bearing or clip, detached.Fig. 4, an inverted or under side view of the same. Fig. 5, a sectionalview of the same taken on line 5-5 of Fig. 3. Fig. 6, a top plan view ofthe next or adjacent oppositely formed clip on the next tooth carryingbar and illustrating the staggered arrangement of the links or reachbars.

Similar numerals of reference designate like parts throughout all thefigures of the drawings.

The improved harrow comprises a plurality or series of transverselyextending tooth carrying bars 1, which, in the present instance, are inthe form of tubular or pipe members, said bars being armed with suitableharrow teeth i which latter may be of any suitable and convenient form.

As a means of flexibly connecting the tooth carrying bars 1, as well asproviding means whereby a limited flexible movement is permitted betweenthe tooth carrying bars 1, and the connecting members, a plurality oflinks or reach rods 2, are provided, said reach rods being arranged instaggered relation and terminating at their ends in link bearing ends orportions'2, preferably bent at right angles as shown, and adapted to bedetachably and flexibly connected to each other by means of improvedlink connecting bearing members or clips 3. The connecting bearings orclips 3, are each provided with oppositely extending link receiving stopmembers 8 and 8", respectively, preferably disposed at diagonallyopposite corners of the clip and terminating in link bearing portions 3,to receive and contain the angularly extending bearing portions 2, ofthe link or reach bars 2,

As a means of retaining the bearing portions 2, of the links in properseated pos1- tion within the link bearing portions 8, un-

' derneath the cli s 3 link retainin or auxbars 1, respectively, asshown and illustrated most clearly in Fig. 2 of the drawings. 7

Thedratt hooks 6, at opposite ends of the harrow. are provided withbearing ends 6, and are secured within the clips in a mannersimilar to"the. bearing, ends 2, of the links, and it is apparent that since thelink stop members 3, extend upwardly and the stop members 33", extendsubstantially horizontal relative to the horizontal planes of the clips3, that when the harrow is drawn in one direction the tooth carryingbars 1, may be permitted to tip upon their axes whereby the teeth mayassume a rearwardly extending position as illustrated in Fig. 1 of thedrawings, and that when the harrow is drawnin the opposite direction,the bars 1, when tipped will bring the teeth 1 in a substantiallyvertical position or at right angles to the links 2, as in the normaloperation of the harrow in pulverizing the soil, as desired: in thisclass or type of barrows.

From the foregoing description, taken in connection with theaccompanying drawings, the operation and advantages of my invention willbe readily understood.

Having thus described one of the embodiments of my invention, what Iclaim and desire to secure by Letters Patent, is,

1. A flexible harrow, comprising transversely extending toothoarryingbars, link connecting bearings detachably mounted thereon,connecting links detachably mounted in said bearings and having alimited movement therein, and link retaining plates beneath saidbearings and links.

2. A flexible harrow, comprising tooth carrying bars, link connectingbearing members mounted thereon, connecting links hav- 7 ing bearingends mounted beneath said bearing members, link retaining plates mountedbeneath the bearing ends of said connecting links, and attaching boltsextendingthrough said tooth carrying bars and said bearing members andretaining plates.

3(A flexible harrow, comprising transtheir ends bent at right anglesthereto, link connecting and retaming members receiving the angular endsof said links and having a limited movement with respect to the latter,and attaching elements for securing said parts in assembled positionupon said tooth carrying bars.

5. A flexible harrow, comprising tooth '1 carrying bars, link retainingclips mounted above the same, link members provided with. right angledbearing portions resting on said link retaining clips, link connectingclips mounted above said link retaining clips and provided withoppositely arranged stop and bearing portions receiving said links andlink bearing portions, respectively, and attaching elements, securingsaid parts in assembled position. 7

6. In a flexible harrow, the combination witha plurality of toothcarrying bars, and link connecting bearing members detachably securedabove the same; of a plurality of links mounted beneath said linkconnecting bearing" members and having .a limited movement therein, andlink retaining clips interposed between the ends of said links and saidtooth carrving bars whereby said links are retained within saidlinkconnecting bearing members.

7. A flexible harrow, comprising tooth carrying bars, link retainingauxiliary clips moun ed thereon, links provided with right angledbearing portions resting on said auxiliary'clips, link connectinghearing clips provided on their under sides with link bearing portionsand at their opposite CO1? I ners with link receiving stop membersextending at different angles whereby said barrow teeth are permitted toassume different angles according to the direction of travel of theharrow. and attaching elements for securing said clips and links inassembled position above said tooth carrving bars.

8. A flexible harrow, comprising tooth carrying bars, link retainingclips mounted above the same, connecting links provided with rightangled bearing ends normally resting on said link retaining clips, linkconnecting bearing members mounted above said link retaining clips andprovided with oppositely arranged link receiving stop members extendingat difl'erent angles and also provided on their undersides with linkbearing portions receiving and containing In testimony whereof I haveafliXed my said right angled bearing ends of said links, signature inpresence of tWo Witnesses. attachin bolts eXt-endin throiwh said cli sand bearing members between said right FREDERICK angled bearing ends ofsaid links and Witnesses:

through said tooth carrying bars whereby A. B. MOLEAN,

said parts are secured in assembled position. C. A. HINEs.
